Advanced oxidation protein products induce apoptosis in thyroid follicular epithelial cells through oxidative stress in Hashimoto's thyroiditis.

Hashimoto's thyroiditis (HT) is a chronic autoimmune disorder primarily driven by T cell. The apoptosis of the follicular thyroid cells plays an important role in HT apart from the lymphocyte-mediated cytotoxicity. Advanced oxidation protein products (AOPPs), resulting from oxidative stress, are known to be involved in various inflammatory diseases.

PMN-MDSCs are responsible for immune suppression in anti-PD-1 treated TAP1 defective melanoma.

Introduction: The transporter associated with antigen processing (TAP) is a key component of the classical HLA I antigen presentation pathway. Our previous studies have demonstrated that the downregulation of TAP1 contributes to tumor progression and is associated with an increased presence of myeloid-derived suppressor cells (MDSCs) in the tumor microenvironment. However, it remains unclear whether the elevation of MDSCs leads to immune cell exhaustion in tumors lacking TAP1.

Construction of cuproptosis-related genes risk model predicts the prognosis of Uterine Corpus Endometrial Carcinoma.

In this study, we demonstrated that endothelial STING expression was critical for STING agonist-induced antitumor activity.

IRF5 as a potential immunological biomarker in lung adenocarcinoma.

Background: In the clinic, the primary conventional treatments of advanced non-small cell lung cancer (NSCLC) are surgery, radiation therapy, and chemotherapy.

Metabolic syndrome has recently been implicated in OA pathogenesis, underscoring the need for novel therapeutic strategies.

Plasma fibronectin is a prognostic biomarker of disability in Parkinson's disease: a prospective, multicenter cohort study.

In a prospective longitudinal study with 218 Parkinson's disease (PD) patients in the discovery cohort and 84 in the validation cohort, we aimed to identify novel blood biomarkers predicting disability milestones in PD. Through Least Absolute Shrinkage and Selection Operator-Cox (Lasso-Cox) regression, developed nomogram predictive model and Linear mixed-effects models, we identified low level of plasma fibronectin (pFN) as one of the best-performing risk markers in predicting disability milestones. A low level of pFN was associated with a short milestone-free survival period in PD.
